The Vestibular Dynamic Inclinometer (VDI) is a sensor motivated bu the human vesitbular system that is made up of two MEMS linear accelerometers and one MEMS gyroscope. The VDI measures dynamic inclination parameters – inclination, angular velocity, angular acceleration and magnitude of acceleration of the base/surface of contact (gravity). http://tinyurl.com/visheshresearch Duration : 0:2:18

Topology Optimization using a GCMMA optimization algorithm and the lattice Boltzmann method to find the optimal material layout for a micro-mixer. Two miscible (Red and blue) fluids enter a channel and should be mixed at the outlet. The evolution of the channel design is displayed on top with green being solid material and white being [...]
3-phase electrostatic rotary stepper micromotor fabricated with Silicon-On-Insulator technology (two-mask micromachining process) Duration : 0:0:47
This design is directly inspired by the ABB German Corporate Research Centre’s: MIROS MEMS Based Paramagnetic oxygen sensor. Kindly search for Dr.Peter Krippner, Dr. Armin Gasch @ ABB DE CRC. They have created a kind of a design which can be used for many other purposes. The commercial aspects of this design I am not [...]
MEMS have many applications and are found in an increasingly large number of products. These are just a few of the areas that integrate MEMS for greater functionality, reliability, and portability. Duration : 0:1:2
This video shows the surface computed from the raw interferograms. The resulting height is in radians of phase at the interferometer’s laser’s wavelength of 633 nm. The purpose of the poke test is to determine the amount of deformation in the surface for a given applied actuator voltage. The actuator displacement force is electrostatic and [...]
This pacman-like animation demonstrates a conceptual microfluidic device in which fluid is flowing through a series of interconnected channels. When the fluid reaches a corner in the channel it experiences an impulsive force which drives it out of the corner. The fluid is wetting relative to the channel surface so surface tension pulls the droplet [...]
The video shows an automatic assembly of fives silicon microparts of 400 µm x 400 µm x 100 µm on 3-levels. Each microassembly subtask is performed using a pose-based visual control which uses a CAD model-based tracker. The assembly clearance is estimated to 3 µm that allows to obtain solid and complex micro electromechanical structures [...]
